Title: Dry type clutch disc
Inventor: TAKEUCHI YASUSHI
IPC: F16D13/68
Filed: 1982-10-21
Abstract: PURPOSE:To provide more simple construction, more small size and greater magnitude of torsion angle by using a cam formed around an output spline hub and a leaf spring which are mounted to input side plates. CONSTITUTION:When a facing 6 and side plates 3 and 4 begin to turn in the direction F, a hub 1 also begins to turn via a leaf spring 9 and a cam 2. As a turning torque of the side plates 3 and 4 is gradually increased, they relatively begin to be subjected to torsional effort with respect to the hub 1 so that leaf springs 9 are increasingly subjected to resilient deformation outward in the radial direction by end members 6 of the cam 2. In association with greater magnitude of a torsion angle, each of the end members 6 makes shifting abutment from spring 9 toward its rear end 9b thereof. After a certain shift, the leaf spring 9 comes into contact with a rubber stopper 10. More further great magnitude may cause the rubber stopper 10 to begin resilient deformation.

Title: Keyboard
Inventor: TAKAMATSU KAZUHITO
IPC: G06F3/02
Filed: 1990-07-13
Abstract: PURPOSE:To prevent the input of undesired keys by invalidating one of two keys that is pushed later when these two keys are pushed at an extremely short interval and at the same time giving a warning to an operator with a buzzer, etc. CONSTITUTION:When the push of a key is detected, a key input interval measuring means 4 measures the time interval counted from the time point when the processing of the means 4 is carried out right before the push of the key. The key input interval value obtained by the means 4 is compared with the comparison value set previously by a comparison value setting means 6 by a comparison means 5. When the comparison value is smaller than the interval value, the processing is transferred to a code conversion means 2. Meanwhile the key input is invalidated if the comparison value is larger than the interval value. Then an error informing means 7 generates a buzzer tone to arouse the attention of an operator. Thus it is possible to invalidate one of two keys that is pushed later when both keys are pushed at an extremely short interval. Then the accuracy and promptness are improved for the key input operations.

Abstract: PURPOSE:To improve the reliability of a needle valve lift quantity detector by providing a shifter interlocked with the lift action of a needle valve in a detection chamber provided on a fuel injection valve and detecting the movement of the shifter via a photoelectric converter using an optical conduction means. CONSTITUTION:When parallel rays from a luminous source 25 are introduced to illuminate the peripheral wall at the tip of the shifter rod 15 in a detection chamber 16 via the outside optical fiber flux 23, if a needle valve 3 is not lifted entirely, the rays are not illuminated to the outer periphery of the rod 15, and reflected rays are hardly generated. On the other hand, if the needle valve 3 is lifted and outer periphery at the upper end of the rod 15 processed as a high- reflectance surface is faced to the end surface 21 of the optical fiber flux 20, reflected rays of a quantity in response to the facing area are introduced to the light receiving surface of a photoelectric converter 26 via the optical fiber flux 22. Accordingly, an output signal proportional to the reflected ray quantity from the photoelectric converter 26 is inputted to a display unit 28 via an amplifier 27, and the lift quantity is displayed.

Title: Printing apparatus and method
Inventor: KAI TAKASHI
IPC: B41J2/385
Filed: 1989-07-20
Abstract: PURPOSE:To perform the printing of an arbitrary image without preparing a new plate or replacing a plate by a method wherein ink is applied to a substrate while voltage is applied to the ink corresponding to an image signal using the electrodes subjected to patterning on the substrate to form an image which is, in turn, transferred to a printing medium. CONSTITUTION:While an ink coating roll coated with ink bonded to an anode but not to a cathode is moved on electrodes 2 subjected to patterning in a stripe form, positive voltage is applied to the electrode at a position where the ink is desired to be bonded corresponding to the signal of an image to be printed and negative voltage is applied to the electrode at a position where the ink is not desired to be bonded in the same way from a power supply 8 by switching due to a driver 1. As mentioned above, by the control of voltage applied to the electrodes subjected to patterning by the driver 1, the ink is applied to the electrodes 2 on a substrate 7 to form an image. Subsequently, the ink on the electrodes is transferred to a printing medium such as paper to perform printing. By this method, it becomes unnecessary to prepare a new plate every time at every image.
